Hello there. I've been attempted to create a Monastic Tradition here on D&D Beyond for the first time, and while slowly learning everything that I can do, which was a lot and I've slowly been learning it all, there is one thing that I found that I couldn't do, or at least couldn't find out how to do it. My Monastic Tradition involves giving the player two additional monk weapons from the martial weapons (akin to the Kensei) but while I saw the Kensei options when working with a copy of the kensei subclass, I wasn't seeing a way to add Kensei or even additional Monk Weapons while looking through the Modifiers section of Class Features.
Not sure if this is something that hasn't been implemented yet or I just didn't look in the right place and missed the option.
Either way, thanks in advance for the response, or directions on where the option I was looking for currently is.

There probably isn't a modifier for this. The homebrew tools can basically only do what other official features have needed. And there hasn't been an official feature that added new weapons as monk weapons besides kensei which also added other features at the same time.

That makes sense that it only adds what other official stuff has been done. I would have figured they would have at least let people use the Kensei option then in the modifiers since the actual subclass has it's own modifier when you look at a copy of it.

Hopefully it's something they'll add down the line, but I suppose being able to customize attacks on the character sheet will have to do for now.
